To all whom t may concern.' 4

Be it known that I, JAMEs H. WALKER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification, reference being hadto the accompanying drawing, forming a part thereof.

The main objects of this invention are to construct and arrange theburners of a gas range or stove and their connections so that they willbe easily accessible and unaffected by the heat of the stove and so thatthe burners may be readily and separately removed for cleaning andrepairing the same; to locate the cocks or valves controlling the supplyof gas to the burners where they will be out of the way and not liableto be accidentally displaced, but can be readily operated by suitableconnections; and generally to improve the construction, arrangement andoperation of the burners and their connections for gas ranges yorstoves. y

The invention consists in the construction, arrangement and combinationof parts as hereinafter particularly 4described and pointed out in theclaims.

In the accompanying drawing like characters designate the same parts inthe several figures.

Figure l is an end elevation of a gas stove or range embodying theinvention; Fig. 2 is a plan view of one end of the stove or range withthe top plate removed; and Fig. 8 is a vertical section on the line 3-3,Figs. l and 2. y

The stove or range comprises a top frame a, a top plate ZJ, end walls c,one of which is shown, and side walls d. horizontal wall c, locatedbelow the frame a, forms with the top plate b and end and sidewalls cand d, a heating compartment or combustion chamber f, which ispreferably divided into longitudinal flues or channels by `partitions g.The heating compartment or combustion chamber f, is provided at thebottom with a lining L of fire brick or other refractory heat absorbingand reflecting material, as shown in Fig. 3.

The stove orfrangel is provided at the end with a number of separatelyremovable burners comprising vertical flues or mixing tubes V,'havingair inlet openings at their Specification of Letters Patent. i

lower flaring orenlarged endsj, and laterally bent upper end or headsZo, which open into the heating compartment or combustion chamber f inthe direction of the length of thelues into which it is divided, andpreferably close to the top plate b.

he burners and their gas supply connections are located outside of thestove or range, where they are unaffected by the heat and are accessibleas well as out of the way.

The laterally bent heads /c at their upper ends are inserted in openingsformed therefor in the end wall c, and are formed or provided with studsor lugs 1, which by engagement with said end wall hold the burners inplace.

.A gas supply ported in a horizontal position across the end of thestove or range by brackets n, at-

tached to the end wall c.

At their lower ends the burners are formed orv provided with centrallyperforated spiders or cross and removably fitted on the nipples o of thecocks or valves p connected with the gas supply pipe or manifold'm, andforming gas passages. between said pipe or manifold and thel lower endsof the flues or mixing tubes d of the burners. Y

Disks g, for adjusting and regulating the supply of air admitted intothe lower ends of the iiues or mixing tubes i of the burners, arethreaded on the nipples 0, as shown in Fig. 3. The burners are looselysupported at their lower ends on the nipples o of the gas cocks orvalves p, and at their upper ends bythe heads 7c in the end wall c ofthe stove or range. They are removably secured in place by a metal bandor bracket r,- fastened to the end wall c of the stove or range, and byclamping bars or bands s, which are connected with theband or bracket rby screws or other suitable means. By detaching the clamping bars orbands s from the bracket or band r, or by turning them into an uprightposition, any of the burners may be readily removed from the stove orrange independently of and without disturbing the others.

VTo facilitate the operation of the gas cocks or valves p, whicharelocated at the end of` the stovel or range where they are out of the.wayand not liable to be accidentally turned or displaced, rods t, arepivotally pipe or manifold m,lis suppieces which are looselyvnot onlyfacilitating the operation of the cocks or valves, but also indicatingat a glance which of them are open and which are closed.

To admit an additional supply of air to the heating compartment Vorcombustion chamber f, or to the flues into which it is divided by thepartitions g, for producing and maintaining complete combustion of theformed in theV end below the disends of the fuel gas, openings are wallc of the stove or range charge openings at the upper burners.

In the operation cocks or valves j?,

of the stove or range the of any desired number of burners according tothe amount and kind of work' to be done, being opened by pullingV theknobs or handles Vfw controlling such burners forward, the combustiblemixture of gas and air issuing from the discharge openings at the upperends of the burnersV is lighted -and produces broad jets or sheets offlame which are directed lengthwise of the flues along and in contactwith the top plate Z2, more or less of which is heated sufciently forperforming .the desired cooking operations thereon.

When the burners have been in operation for some time, the'fire brick orother refractory bottom lining h of thev combustion chamber becomesincandescent or highly heated, reflecting heat to the top plate andaidingcombustion of the fuel gas.

After the refractory lining and walls of the combustion chamber or iueshave become highly heated, the gas supply toKV alternate burners or tosome of the burners may be Vshut off, and the required degree of heatfor such cooking operations as are in progress..

may be maintained by the operation of the remaining burners. When asmall or limited amount of cooking is to be done,

Yonly that portion of the top plate which is required, Vneeds. to beheated, the burners supplying other portions remaining out of ifise,thus economizing in the consumption of uel. Y

' ylhe location of the burners entirely outsideV of the stove or range,not subjected to great variations of temperature, avoids variationsinthe supply of air thereto and inthe resulting mixture of air and fuelgas, thereby maintaining the proper quality of the burner flames Vforthe production of the greatest amount Vof heat for a Vregulation of thegas and air where they areV given consumption of gas, whatever length oftime the burners may be in use. This location of the burners alsoprevents carbonization and reduced efficiency thereof resulting invariation in the temperature and overheating of the mixture beforeignition takes place, and avoids the necessity of constant attention andfrequent adjustment and supply to the several burners.

The construction and arrangement of the burners shown and described alsoadmit of readily removing any of the burners for cleaning, repairing orrenewing the same independently ofthe others, and afford easy accessthereto as well as to ytheir gas supply connections and controllingcocks or valves and the adjustable disks Q, for regulating the supply ofair to the lower ends of the vertical flues or mixing tubes of theburners.

Various modifications in minor details of construction and arrangementofparts may be made without departing from the principle and scoperof theinvention as defined in the following claims. j Y
